Unexpectedly, Kotaro finds himself with tickets to Runrune Resort, a destination overseen by Alice. Upon arrival, Puniru resolves to captivate, and her ambition to appear more charming than ever might well ignite unforeseen adventures.

Kotaro, a solitary figure yearning for Puniru’s return, often observes the results of her charm training from a distance. Then, quite unexpectedly, a package arrives.

He arrived in a realm of myth and wonder, and quickly discovered his purpose: to rescue Princess Kyuthi from the Demon Lord’s fortress, where she was held captive.

Following Runru's malfunction, Puniru resolved to administer a restorative concoction of slime-based medicine. The remedy, however, produced an unforeseen consequence: it stirred within Runru a nascent awareness of self.

Mado achieved the remarkable feat of creating a lifeform of artificial slime, and she christened it Gelee. Yearning for a deeper understanding of humanity, Gelee embarked on a quest to find someone worthy of affection.

Kotaro harbored ambitious plans for the coming summer, though a nagging question lingered: might he be his own undoing? Elsewhere, Puniru was striving to amplify his strength.

A certain girl, Gelee, drew the attention of many of the school's boys, including Kotaro, a fact that irritated Puniru considerably.

Alice extended an invitation to Kotaro to spend time at Runrune Resort, yet his thoughts remained consumed by Gelee and her persistent attentions.

Gelee’s arrival in Kotaro’s class was not a welcome one, much to her own dismay. Simultaneously, Puniru was meticulously orchestrating a grand surprise for Halloween.

Hodai conceived a plan to undermine Kotaro's standing with Alice, proposing a contest of artistic skill against Nanpa.

A heated argument erupted between Kotaro and Puniru, culminating in Puniru fleeing to Mami’s apartment. There, he encountered the Kirara family.

Kotaro maintained a study group with his friends, yet a thoughtless comment directed at Gelee would ultimately unravel with serious repercussions.

Puniru underwent a transformation, becoming a girl indistinguishable from a human, yet Kotaro’s reaction to the news lacked the universal joy of others.
